BGO (Bismuth Germanate) is a high-Z, high-density scintillating crystal. The material has a high atomic number (Z=83 for bismuth) and a density of 7.13 g/cm³, making it a highly efficient gamma-ray absorber.
Due to the high-Z properties of the material, the gamma-ray-induced light absorption fraction is significantly enhanced, resulting in an excellent peak-to-total ratio.
Cesium iodide (CsI(Tl)), activated by thallium, is one of the most efficient scintillators discovered so far. CSI Crystal exhibits thallium-activated luminescence with an emission peak at 550 nm and a light output of 45% relative to NaI(Tl). In contrast, cesium iodide activated by sodium (CsI(Na)) features a sodium-activated emission peak at 420 nm and a higher light output (85% of NaI(Tl)). Both materials share properties such as deliquescence, soft and plastic mechanical behavior, radiation resistance, high-temperature tolerance, and fast timing characteristics (for pure CsI). They are widely used in particle detection for high-energy physics experiments, medical SPECT imaging, baggage/container security inspection, industrial level sensing and non-destructive testing, and cosmic ray research in space physics.
